Specification 01' Letters Patent.

Patented Feb. 22, 1916.

Application filed. March 27, 1914. Serial No. 827,649.

To all whom it may concern:

Be it known that I, JOHN P. DORAU, a citizen of the United States,residing at Jefferson, in the county of Jefferson and State ofWisconsin, have invented a new and useful Clothes-Founder; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to clothes pounders and the like. It is a deviceto facilitate the washing of clothes in the tub, being capable ofperforming the maximum amount of work with the minimum expenditure ofenergy. IVhile designed to give the greatest strength in the simplestmechanical struc' ture, it can be easily and cheaply made and will,therefore, more universally commend itself. The pattern herewithillustrated is thought to embody the'most eflicient design.Nevertheless, the inventor reserves the right to make any changes oralterations that are not foreign to his appended claim.

In the drawings :'Figure l is a planview of the improved clothespounder. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is asectional view on line 33 of Fig. 2. Fig. 4 is a sectional view on line4- of Fig. 2.

The device consists essentially of the air' chamber '1 having the sidewalls 2 and the top plate 8. The cylindrical rib 4 runs around theentire lower edge of the walls 2 and besides giving added strength tothe chamber 1 forms a rounded edge that will not tear or mar theclothes.

The air chamber is so shaped that it has its greatest width andtherefore its greatest volume at points remote from the center and whenit is remembered that the greater bulk of clothes is away from thecenter of the tub, the advantage of this increased volume is readilyapparent. I

In Fig. 1 the relative proportions of the pounder and tub are shown, thetub being designated by the letter T.

A casting 5 serves as a support for the air chamber to which it issecured by the screws 6. This casting also carries the operating handle7, the pin 8 serving to hold said handle in position. 1

A check valve is included in the design of the casting 5, the air inlet9 leading to the ball valve 10 and the air outlet 11 into the airchamber 1.

The pounder is operated by imparting to it a reciprocating motion and atthe same time an intermittent rotary motion and this may be done eitherby machinery or by hand.

If a machine is used, any conventional forms of combining a constantreciprocatlng motlon with an mtermittent rotary motion may be employed.

on valve 10 is released and equilibrium is restored by the inrush of airthrough the inlet 9. The repetition of these movements followed by thecondensation and rarefaction of the air very quickly rids the clothes ofall dirt without the harmful effects which I invariably followscrubbing.

The invention having been set forth, what is claimed as new and usefulis I A valve structure for a reciprocating casing, comprising a castingextending through the upper wall of the casing and depending below thewall, a duct formed in the-casting and passing from the upper surfacethereof downward in the casting to a substantially elbow turn andprovided with a valve seat adjacent to the'termination of the elbowturn, said duct then extending upwardly substantially parallel with itsdownwardly value seat being larger in diameter than the right-angledoutlet opening, said upwardly extending portion immediately abovetheextending portion and terminating in "a valve seat and the first part ofthe. duct,

and a ball valve cooperatingwith the seat.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
